When two boats share the same hull type — in this case both the Mercury 350 Ocean Runner Hypalon 2011 and the Mercury V620 PVC 2010 are inflatable rigid designs with plastic construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Mercury V620 PVC 2010 measures 20,2 feet overall (2010), giving it roughly 8,7 additional feet of deck space compared to the Mercury 350 Ocean Runner Hypalon 2011 at 11,5 feet (2011). Weight tells a clearer story for trailering families: the Mercury V620 PVC 2010 tips the scales at 1 071 lbs — 868 lbs less than the Mercury 350 Ocean Runner Hypalon 2011 at 203 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 150 hp, the Mercury V620 PVC 2010 has a 125-hp advantage over the Mercury 350 Ocean Runner Hypalon 2011's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Mercury V620 PVC 2010 is rated for 17 passengers, while the Mercury 350 Ocean Runner Hypalon 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury V620 PVC 2010 could be the deciding factor.
Bottom line: Choose the Mercury V620 PVC 2010 if your priority is putting more people on the water — it handles 17 passengers and at 20,2 ft it has the deck room to back that rating up comfortably. The Mercury 350 Ocean Runner Hypalon 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
